IMPROVEMENT lN CAR-DOOR-HANGING DEVICES.'

Specification forming part of Letters Patent' No. 184,983, dated December 5, 1876; `application led October :14, 1876.

1 0 all whom it' may concern: I Be it known that I, ELIAS E. PRATT, of

j'wNorwood, in the county of N orfolk, State 'of Massachusetts, have invented certain new and useful Improvements in Devices for Hanging Gar-Doors, of which the followingis a de- Scription suiioiently full, clear, and exact to enable any person skilled in the art or science to which my inventionv Vappertains-to `make tached portions of tbexsame; and Fig. 2, -a

vertical cross-section, showin-g the suspensory hanging devices.

Like letters of 'reference indicate. corresponding parts in the different igures of the drawing. Y

My invention relates especially tothe doors of' freiglitcars; and consists in a novel' construction and arrangement of the parts, as hereinafter more .fully set forth and claimed, by which a simpler, cheaper, and more effecti ive means for hanging and operating such doors is produced than is now in ordinary nse.

11n' the drawing, A represents the side of car, the run'letB, provided with the anges the car; G, the door, and P the opening in the car which the door is designed` to close. 1m mediatelyabove this opening there is a run- `let, B, attached tothe side or body of the. car

by the screws an j. This runlet isA providedl with inwardly-projecting lips or flanges C near its base, forming a track, on which-the Asheaves or grooved. trucks D traverse, the' door G being suspended on the sheaves by means of the laterally-elongated staples or lu'gs F, which work in a Vslot betweenthe flanges'.

The lower end of the door is provlded with astrap, I, and is prevented from swinging.

outwardly by the friction-roller H. The end of this strap is elevated at the rear edge of tinA door by means of the lift or wedge n, so' that when the door is closed the thickenededge ofthe same, comingin'to lcontact with the roller H, will cause the door to be pressed inwardly, and make a tight joint at that section of the opening P.` Substantially the same result is accomplished at the front edge' of the doorby means of the strap'K, which is providedwith' the cam-shaped projection or dog m,`,tting into a correspondingly-im clined socket (not shown) in ltheframe of the door, so thatwhen the door is closed the in' eline m, striking the inclined side ofthe socket, will force this part of the door inwardly, and

also form a. tight joint, eifectually preventingA the entrance of sparks,` dust, & c;, fromvwithout.

The top, sides, and track ofthe runlet B are of metal, and`preferablycast integral, the formation f the runlet being such as to completely house orccver the track," sheaves,

links, and top ,of the door,l and prevent the` working parts describedfrom clogging with snow and ice. The elongated' staples or l lugs F give free play to the sheaves, and pre- -vent the parts from cramping or binding in moving the door.

Having thus explained my improvement l what I claim .is-

1. -In the device for hangingthe door of a C, and otherwise constructedfand` arranged to operate substantiallyv as set forth and Aly asset forth.

4. :The inclined projection m, in combina.- tion with the door G, substantially as set forth .and specified'.
